Please explain CL_KERNEL_PREFERRED_WORK_GROUP_SIZE_MULTIPLE

Hi, everyone.

I'm pretty new to openCL and gpgpu.

I've read in different places that CL_KERNEL_PREFERRED_WORK_GROUP_SIZE_MULTIPLE is related to or similar to warps and wave fronts, but isn't quite the same thing. Could someone explain the difference or point me to an explanation?
Also, is there another way of querying for the "warp size" on a non AMD or Nvidia device?

(I'm sorry if this is a done to death thread, but I wasn't able to find anything when searching the forum)
